Paul McCartney headlined PETA’s 35th anniversary gala last night (Sept. 30) in L.A., and he brought out Beck to perform a series of Beatles classics.

See them play “I’ve Just Seen a Face” in the fan-shot video up above. Then, watch a snippet of McCartney and Beck’s performance of “Drive My Car,” plus a video of McCartney on the piano for “Let It Be,” in the Instagram clips at the bottom of the page.

Following the performance, McCartney took to Twitter to share his terrifically punny gratitude to both Beck and PETA. “Thanks to @Beck and everyone at #PETA35,” he wrote this morning. “Sorry we didn’t get to play Beck in the USSR, Get Beck or Paperbeck Writer!”

Beck unveiled “Dreams,” his first new song to emerge since his Album of the Year-winning Morning Phase, back in June. There’s still no word as to whether or not that track will appear on a forthcoming full-length from the singer-songwriter.

In the meantime, Beck will contribute to the covers compilation, Echo in the Canyon -- a tribute album to ‘60s Southern California folk-rock. He’ll also play a corresponding concert at L.A.’s the Orpehum on Oct. 12. Fiona Apple, Cat Power, Regina Spektor and more are also set to appear on the album and at the show.
